Measuring Bias: Kate Zernike Shares How Exceptional Women Are Not the Exception

A tape measure may seem an unlikely tool to identify unconscious bias within an organization, yet in the hands of biologist Nancy Hopkins, it quantified gender bias and became a powerful symbol of the fight for gender equality. 

During the most recent Scientists & Strategists lecture, hosted by the Carnegie Mellon Institute for Strategy and Technology (CMIST), guest speaker Kate Zernike recounted the story of Hopkins’ quest to unveil gender bias while working at the Massachusetts Institute of Technology’s Center for Cancer Research, later renamed the Koch Institute for Integrative Cancer Research.

A renowned journalist for The New York Times since 2002, Zernike connected with Hopkins in the spring of 1999 while working as a reporter for The Boston Globe, eventually breaking the news of MIT’s historic admission of discrimination against women. Years later, in 2023, Zernike published a book based on the full story of Hopkins’ journey titled The Exceptions: Nancy Hopkins and the Fight for Women in Science. 

The Scientists & Strategists event began with a welcome by CMIST director Audrey Kurth Cronin, who expressed great pride in the prominent roles of women at Carnegie Mellon University (CMU) in the fields of science, engineering, and humanities before turning the stage over to Provost Jim Garrett. 

The Provost acknowledged progress since the days of the Margaret Morrison Carnegie School for Women, but stressed that fostering belonging, equity, and inclusion remains a top priority at CMU as “there is always work to be done.”  Before introducing Zernike, Garrett highlighted the importance of the evening’s discussion, noting that with the right environment, diversity allows us to do better work and find better solutions. 

The daughter and granddaughter of physicists, Zernike was surrounded by science as a child.  She was also inspired by the story of how her mother, who was initially discouraged from pursuing law, earned her Juris Doctor at the age of 45. So in March 1999, when Zernike received a “vague tip” that something was going on with women in science at MIT along with a suggestion to contact Nancy Hopkins, she knew she needed to find out more. 

What started as a curious phone call soon sparked a nationwide conversation about gender bias as well as a longstanding friendship between Hopkins and Zernike.

During her talk, Zernike guided the audience through the at times infuriating, at times entertaining story of how this brilliant molecular geneticist and cancer researcher uncovered pervasive inequities at MIT by utilizing a skill she was well-trained in: collecting and analyzing data. 

The catalyst of this ground-breaking discovery was a simple request by Hopkins in the early 1990s for 200 square feet of additional laboratory space. Hopkins, who by then was a tenured faculty member with over a decade of experience at MIT’s Center for Cancer Research, needed the additional space to house the fish tanks for her research into gene expression in zebrafish. After her request was denied, she decided to compare the size of the laboratory spaces afforded to male faculty members at MIT, including those junior to her. 

As Zernike explained, Hopkins “did not set out to be an activist '' nor a feminist. A strong believer in meritocracy, Hopkins had actually gone out of her way to prove that what was happening to her was not discrimination, thinking that any disparities in treatment must be attributed to deficiencies in the quality of her work. However, the data she collected told a different story.

Using a measuring tape now on display at MIT, Hopkins literally got on her hands and knees to collect the measurements. She found that most male faculty members of similar rank at MIT had between 3,000 to 6,000 square feet of laboratory space as compared to her 1,500 - and that even junior male faculty averaged 2,000 square feet.

After confiding in a friend about her discovery, Hopkins found validation when other women faculty members shared similar stories of bias. Nearly all (16 of 17) female faculty members surveyed at MIT signed Hopkin’s report based on the collected data, which presented an evident case of bias to the university leadership. Ultimately, the president of MIT at the time,  Charles M. Vest accepted the findings of Hopkin’s report and made a public declaration of support regarding claims of gender discrimination.

Hopkins told Zernike that it took 20 years for her to realize there was gender discrimination occurring - 15 years to see it was happening to others and another five to recognize it was happening to her. The bias was not overt, but rather evident through small actions, such as being excluded from decision making, having others take credit for her ideas or work, and of course the spatial bias in lab allocations. 

The fact that gender bias did not present itself in the way Hopkins had expected calls attention to an ongoing challenge. Zernike pointed out that unconscious bias can happen even at a university that views itself as progressive, such as MIT. Therefore, it is vital to continue the conversation, because “things slide backwards if we don’t keep pressing forward.” 

Zernike left the audience with an unsettling insight taken from the title of her book. While all the women in the book were exceptional, they also viewed themselves as the exception - the one-off. This self-perception led them to believe that the discrepancies they encountered were a result of their individual efforts rather than the symptom of a collective issue.

Yet Hopkins’ story is a hopeful one that shows the importance of open communication and collective action to address a systemic issue. In Zernike’s words, “there is power in women working together, and people working together.” She emphasized that collectively we are able to change culture, and when the culture begins to change, so does bias. The way forward can be found within us, in how we perceive and recognize women, because exceptional women are all around us.
